It took me a week to listen to the whole thing off and on. Still, I would say that despite the length, the density of ideas is high. In fact, I briefly considered just starting it over again. I think some of his stuff is off base, but even those observations are thought-provoking.
My wife was more skeptical than me, but had the same reaction - surprised to make it all the way through, but then feeling like it might be worth a second listen.
I guess it depends on how much you know about the topics. For us, on the subject of crypto, the answer was, "close to nothing." So if you're better-informed, it will no doubt be less thought-provoking.
The one-hour version on "What Bitcoin Did" is more focused, but less interesting. But for the specific topic that started the thread, has the kernel of it.
